Electro-stimulation device and method of systematically compounded modulation of current intensity with other output parameters for affecting biological tissues

ABSTRACT

A non-user controllable electro-therapy device has a housing for a microprocessor, power source, status indicator, activation switch, and one or more channels for electrode contact. Only the activation switch is user-accessible. The microprocessor generates a non-user controllable frequency dependent mixed electrical signal through the electrodes, wherein the mixed electrical signal is a combination of at least two different frequencies, a first frequency having a first minimum and maximum microamp range and a second frequency having a different second minimum and maximum microamp range. The higher of the two frequencies is superimposed on the lower frequency, creating a current intensity window as an envelope along a profile of the lower frequency. The mixed electrical signal is automatically applied for a pre-determined period of time, and amplitude and/or duration and/or frequencies is varied according to a pre-set schedule programmed into a controller coupled to the one or more electrodes.

FIELD

This invention relates to electro-stimulation schemes for treatment of biological tissue. More particularly, it relates to low to no supervision designs for specially modulated electro-stimulation of tissue.

BACKGROUND

Clinical electrotherapy devices have been used for over a century to treat many types of medical problems. During the past several decades, Transcutaneous Electrical Nerve Stimulation (TENS) has been used successfully as an alternative or adjunct to drugs for the symptomatic relief and management of pain syndromes. Typically, TENS devices temporarily block pain sensations by providing a milliampere level electrical signal that interferes with the ability of the affected nerves to transmit the pain signals to the brain. A problem with this electrical stimulation is the process known as habituation, accommodation or tachyphylaxis. Essentially, with increasing duration of TENS pain treatment approaches, the stimulated nerves become habituated to the electrical current, diminishing treatment efficacy. While TENS is known to block pain, it is not known to promote tissue healing.

With respect to the latter, Microcurrent Electrical Nerve Stimulation (MENS) therapy, which is at lower microampere levels, has shown tissue healing effects. However, the suite of MENS devices on the market have very specific restrictions on their abilities. For example, limited number of frequencies, a limited range of current intensities, some with timers, waveform/polarity limitations, and so forth. All of these prior art systems involve detailed setup and require active “during-treatment” control and adjustment. Consequently, the prior art devices having many user controlled functions and adjustments that are difficult to manage, are not adaptable for treating “mobile” tissue, such as animals. Therefore, the prior art's long term treatment sessions invariably require constant monitoring by the treating specialist, resulting in poor effectiveness.

Accordingly, there has been a long-standing need in the electro-treatment industry for devices and/or methods that allow minimal to unattended supervision of the treatment, while providing effective treatment. Solutions to these and other shortcomings in the prior art are addressed in the below detailed description.

DETAILED DESCRIPTION

Electrotherapy devices of the related art are limited to blocking pain, promoting healing of dermal wounds, non-healing bone fractures, disease of the macula, and exercising and/or massaging muscles or dispersing lymphedema.

For example, Cheng et al., Arch. Dermatol., Vol. 129, pp. 264-271 (1993), reported an experiment involving the conducting of electrical currents through rat skin submerged in a buffer to study the effect of electric current on glycine incorporation into proteins and on the alpha-aminoisobutyric acid uptake by skin cells. Constant currents from 100 to 600 microamperes were used during incubation of the rat skin in solution for a period of up to four hours at 37 degrees Centigrade. It was reported that, at this low current, the synthesis of ATP was increased. However, at currents over 800 microamperes, that effect was lost.

Wood et al., Arch. Dermatol., 129, pp. 999-1008 (1993), reported the treatment of decubitus ulcers using pulsed, low-intensity direct current (“PLIDC”). A PLIDC instrument (MEMS CS 600, Harbor Medical Inc., Minneapolis, Minn.), an investigational exempt device, was used with a 12 volt battery to provide current breakthrough across the ulcer of 300 microamperes followed by treatment at 600 microamperes. The current was pulsed starting negative with a frequency of about 0.8 Hz.

A variety of U.S. Patents (e.g. U.S. Pat. Nos. 2,622,601, 2,771,554) involve TENS devices that vary the rate, amplitude or pulse width of the generated electrical pulse in a singular way. Typically, accommodation would still occur unless an individual manually adjusted the controls extensively during the treatment. The process was mentally and physically demanding and no one can accurately and quickly adjust manual controls in a manner that taps the potential maximum pain relief provided by non-user controlled means. For example, U.S. Pat. No. 4,019,519 (Geerling) discloses a unit having only its amplitude adjustable. U.S. Pat. No. 4,084,595 (Miller), and U.S. Pat. No. 4,759,368 (Spanton) disclose TENS devices in which the stimulus signal has a manually and independently varied rate, amplitude and pulse width. To provide improved output pulse compensation, one TENS device (U.S. Pat. No. 5,184,617 to Harris et al.) provided manual adjustment of pulse width control linked to a predetermined change in range of intensity of the pulses. Although various types of programmed and manual variation enabled one to deal with accommodation, pain relief in milliamperage TENS devices is a function of the relationship between the strength of the current intensity and the duration of that impulse. The relationship when plotted graphically is known as a strength-duration curve. U.S. Pat. No. 2,808,826 (Reiner), disclosed a unit that permitted instantaneous changes in pulse width and amplitude to two pre-set points along the strength-duration curve. U.S. Pat. Nos. 4,340,063, 4,431,002 and 4,442,839 (Maurer), disclose units with modulation of amplitude, pulse width, and repetition rates, but the problem of accommodation still existed.

MENS therapy has recently been shown to have other beneficial effects that go beyond TENS pain blocking theories. MENS has been shown to have significant effects on diminishing inflammation and edema as well as positive effects on collagen and cellular ATP promotion. However, these benefits are limited by the therapeutic concepts utilized by those doing the programming of the electrical output capabilities of the devices available today, the amount of time that a practitioner can monitor the application of therapy as well as the number of times this limited therapy can be repeated. For instance, the process of repairing microtraumas in the periosteum and bone of equine bucked shins cannot only be attributed to the anti-inflammatory effect reported in the literature with certain forms of microcurrent, for if that was the case treatment with strong veterinary anti-inflammatory medications would be adequate primary therapy. Anti-inflammatory therapies are used adjunctively in bucked shins, but are not known to heal the damaged tissues.

Despite the above breath of knowledge in this field, none of the above contemplate an embodiment for a therapeutic technique of modulating the current intensity function as a waveform being driven between two systematically changing maximum and minimum microamperage values while simultaneously carrying a systematically changing DC or AC frequency among other modulatable output parameters in a single or multi-channel system. The application of this method has been demonstrated by the inventor as not only providing pain relief, but also in healing of human and animal tissues; and reveals an electrotherapeutic technique of compounding the biophysical effects of combined waveforms.

A further complication in the prior art is that the administration and monitoring of electro-therapy is an issue when treating an injured or sore horse or dog with prior art devices. While treating equine or canine conditions with prior art devices, therapy can only be administered as long as the practitioner is willing to monitor the animal, manipulate the device, confirm positive electrode contacts and keep the animal from biting or stepping on the wire leads connecting the device to the electrodes. This limits the practitioner's ability to adjust electro-therapeutic outputs, restricts unattended treatment time as well as the total time per session that therapy can be administered, as well as the cumulative time across treatment sessions. These multiple monitoring requirements decrease the horse or dog owner's and trainer's interest and motivation in applying therapy in an attempt to benefit the horse or dog. Since prior art devices are typically human-based systems crudely adapted for animal use, they have not been effectively used in therapy for unattended animals, such as horses or dogs.

Another difficulty is the fact that the intensity control functions of prior art electro-stimulation devices are user controlled, with a manually adjusted interface, which can be complicated and challenging when the user tries to decide how to control and adjust the settings for current intensity of each channel, frequency, duty cycle, pulse duration, waveform, waveslope, etc. Often, the user may have little or no rationale for adjusting the device a particular way. Connecting wires and other user controls are difficult to manage even by those well trained in the art. The rationale for user controlled intensity function is based in the belief that higher current intensities are a requisite to block pain perception.

The dosage and modulation of electro-therapy in prior art devices is determined by the practitioner's level of motivation to adjust the device during the entire treatment process. Clearly, low practitioner interest or training in how to use the device results in a minimally changing (which can be less effective) treatment program. While, high practitioner interest results in poorly standardized, multiple dosages of different intensities, non-repeatable adjustments based on the subjective observation of the human, horse or dog's behavior and response to treatment, and indiscernible intuition. It is indisputable that devices with multiple user controls breed treatment sessions that cannot be standardized or reproduced. As with any type of medical intervention, unstandardized treatment or medication dosage tends to decrease effectiveness.

Prior art devices are configured with a manually controlled, minimally changing current intensity control function to prevent nerve habituation, accommodation or tachyphylaxis to an unchanging electrical stimulus by increasing the intensity of the electrostimulation as the nerves gradually accommodate to the previous set point.

In view of the limitations in the prior art, both in current waveform type and application methodology, a non-user controlled, specially modulated low current intensity, microcurrent electrical therapy design is described. For example, one embodiment has a programmable device with precise non-user accessible controls (over current intensity and frequency) producing a standardized therapeutic sequence and dosage of electrotherapy with resultant increase in reliability of results. Further, various new embodiments for non-wire lead based electro-therapy are described. For example, another embodiment has a miniaturized device mounted directly to an electrode (of a multitude of designs) without wires thereby facilitating usability in both human and animal applications.

The mechanism of action produced by the therapeutic techniques disclosed herein is hypothesized to be due to one or more of the following: increased perfusion and/or vasodilation secondary to nitric oxide induction; enhancement of stem cell attraction, and/or migration, and/or implantation, and/or stem cell induction, etc.; anti-inflammatory effect due to modulation of cytokines, neuropeptides and other pro-inflammatory substances; anti-edema effect due to regulation of intracellular water and ion balance vs. extracellular water and ionic balance; regulation of cellular physiologic balance (e.g. between osteoclasts and osteoblasts in bone formation), systemic and local hormone and peptide release as well as cell-to-cell messenger signaling systems and activation of cell membrane proteins by electrical means, hence the potential to influence gene activation through this cell membrane receptor mediated method.

Accordingly, the intensity modulation capability of one or more of these embodiments is believed to significantly improve electro-therapy treatment responses in conditions such as: Pain, Inflammation, Shingles pain (Varicella zoster), Macular Degeneration, Psychological Mood, skin Cosmetic concerns and wrinkles, nausea, PMS, injury or trauma, wound healing, etc. The ability to improve or potentiate Iontophoresis treatment responses and/or depth of penetration of the involved compounds and/or medications(s), is also believed to be enhanced. Electro-therapy treatment, previously known in the prior art to be unresponsive or inefficacious for Hepatitis, Nephritis, Interstitial Cystitis, high blood pressure, Benign Prostatic Hypertrophy (BPH), Prostatitis, etc., can be effectively treated by various embodiments described herein. Various embodiments are understood by the inventor to positively affect cellular physiologic and/or nuclear (e.g., genetic, etc.) structure and/or functioning in tissues not only in vivo, but also in vitro, as well as improving or potentiating cellular electroporation methods known in the art.

Various embodiments are understood to have the ability to influence biological systems at a cellular level, organ level and organism level, including rate of cellular proliferation growth rates (both enhancing and inhibiting) as well as differentiation into the various specialized cellular sub-types as well as de-differentiation, cellular telomeric attrition, cellular membrane phospholipid dynamics, cellular membrane protein activation and/or deactivation; hormonal, immunologic, peptide, protein and other cellular signaling systems; up regulation and down regulation of various genes of interest, etc.

Details of these and other embodiments with their capabilities and therapeutic techniques are further described below.

FIG. 1 is an illustration 100 of a self-enclosed embodiment on the back of a horse 110. A protective housing 130 contains the (not shown) power supply, a microchip or microprocessor, associated frequency/current controller, active state indicator and one or more channels for applying microamperes of electrical current to the skin of the horse 110. The channels are coupled to embedded electrodes and/or current paths in the pad 120 to contact desired treatment areas. The controller device is not user accessible, being encased in the protective housing 130, and provides a programmatically controlled, systematically changing amount of current in each channel from about 0 microamperes to about 600 microamperes. The frequency function is programmatically controlled, by the microprocessor, and systematically changing from direct current to about 1,000 Hertz or more. The other parameters of electrical output such as duty cycle, waveform, polarity, etc. are also programmatically controlled and systematically changing.

The above embodiment is representative of one of many possible configurations, but exemplifies a commercial embodiment, with the specified current and frequency values, that has been used for treating animals. Of course, other configurations, modifications, applications are possible and, being within the purview of one of ordinary skill in art, are within the scope and spirit of this disclosure.

FIG. 2 is an illustration 200 of an exposed controller comprising circuit board 210, microprocessor 220, battery chamber 230, two channels 240 for electrode contact having outer “snap-in” collars for attachment, and input/output pin 250. DC/DC step up converter 260, on/off switch 270, status light 280, frequency crystal 290, with discrete circuit elements are disposed about circuit board 210. Battery chamber 230 houses the battery (one or more may be used to obtain the desired voltage/current). Microprocessor 220 (or associated memory) contains the program for controlling the output such as duty cycle, waveform, polarity, etc.

In some embodiments, channel 240 may be connected to only one electrode, according to design preference. An instance where this could occur would be if the subject had a natural polarity opposite to the single channel 240. Or, a buildup of charge is intended by the therapy.

FIG. 3 is an illustration of an exposed controller 310 attached to an electrode pad 320, with batteries 335 installed. The overall shape of this electrode pad 320 is designed to be symmetric to allow the entire pad to rest in a balanced manner over the horse's back (or other subject feature). Symmetry keeps the electrode pad 320 balanced so as to minimize slipping during slight movements by the horse (human, plant and/or microbial tissue) and also with its extended surface area and adhesive properties of an electroconductive hydrocolloid gel provides sufficient downward force to ensure that the underside electrodes physically contact and adhere to the tissue as well as conduct the current through the hairy coat of an animal.

As to the specific shape and size of the electrode pad 320, it can be sized to provide a range of “current densities” as it disperses the current from the controller's channel(s) to the anode and cathode. In a commercial embodiment, the electrode pad 320 uses a 64 square centimeter dispersion surface area for the anode and another 64 square centimeter dispersion surface for the cathode. A “Shuriken” (hexagonal shape with extended edges) shape creates a dispersion surface that increases the perimeter length of the pad's electrode relative to the central energized area of the pad's electrode, encouraging a dispersion gradient from the central area of the pad's electrode to the perimeter that changes/pulses partly as a function of the distance from the central discharge area and partly as a function of the waveforms changing with the controller's current management program.

The extension “nubs” (or undulating edge) of the electrode pad 320 also serve to improve the ability of the electrode pad 320 to form to curved surfaces of the subject's body, therefore improving treatment effectiveness by improving body surface contact/tissue electrodispersion. These extension “nubs” also improves usability, in contrast to a typical medical device (electrode) that traditionally utilizes square, circular and rectangular designs that are built for ease of manufacture, but not for facilitation of electrotherapy to a body composed of very few flat surfaces.

In a commercial embodiment, the electrode pad 320 is configured to have mating snap connectors to allow the controller 310 to “snap” into the electrode pad 320, to form the electrical connection and also be secured to the electrode pad 320. The makeup of the electrode pads 320, depending on application, can be composed of a material that has been tested for biocompatibility, allergenicity, cytotoxicity, and engineering verification and validation. Depending on implementation, the electrode pad 320 may need to be FDA compliant, or compliant with any other medical device/treatment approving body.

FIG. 4 is a block diagram 400 of a device embodiment. Power source 410 is coupled to an on/off switch 420 which is connected to a boosting converter 430, which boosts the power source 410's voltage to a higher level (if power source 410 is of sufficient voltage/current, then boosting converter 430 may be bypassed or deleted from the design). The boosted voltage is channeled via power rail 435 to status indicator electronics 470 which feeds status indicator 480. The status indicator 480 will typically be an LED, but may be another light emitting device, and/or be proxied by a sound emitter. Status indicator electronics 470 can generate a blinking/varying signal to status indicator 480, or may be a steady state signal. Of course, other types of signals and/or indicators 480 may be used without departing from the spirit and scope of this disclosure. Moreover, more than one status indicator 480 may be utilized, according to design preference.

Power rail 435 (or by separate connection from power source 410—not shown) carries power to microprocessor 440, which contains the program/instructions for controlling the output such as duty cycle, waveform, polarity, etc. The program may be activated by initiation of the on/off or momentary switch 420 or upon some other trigger. Microprocessor 440 has output channels 450, 460 which are the channel electrodes forwarding the current signals to the subject. Various resistors/switches/controls 445 may be switched on/off via signals from microprocessor 440, to modulate/alter the output current to output channels 450, 460.

This embodiment contemplates the frequency control to be part of the microprocessor 440. That is, frequency control actions are facilitated by software instructions. However, the actual frequency “source” may be a clock signal external to the microprocessor 440 or internal to the microprocessor 440. Understanding that some clock sources can generate multiple frequencies, more than one clock source may not be necessary. Therefore, microprocessor 440 may rely on internal frequency changing/amplitude changing capabilities or rely on other chips (not shown) that may be more effective in providing the desired control. Therefore, multiple chips may be used according to design preference. Aspects of microprocessor and/or chip level control/manipulation of signal frequency and amplitude are well known and, therefore, the details thereof are within the purview of one of ordinary skill in the art.

FIG. 5 are illustrations of various electrode pad configurations with attached controller. The lower illustration shows an embodiment 500A with electrode pad 520A and controller 530A attached thereto. Pad 520A is shaped as a horse-shoe so as to rest over or fold over a neck, back, or shoulder, etc. The middle illustration shows an embodiment 500B with electrode pad 520B and controller 530B attached thereto. Electrode pad 500B is shaped as a long “double shuriken” to cover larger areas for treatment (e.g., horse's hind quarters). The upper illustration shows an embodiment 500C with electrode pad 520C and controller 530C attached thereto. Electrode pad 500C is shaped as a small double shuriken for smaller treatment areas. It is noted that these embodiments show symmetrically shaped electrode pads 520A, 520B, 530B. Of course, it may be desirable in some embodiments to have non-symmetric electrode pads or of differently shaped electrode pads. Therefore, these considerations of shape and symmetry are dependent on the application and accordingly may be modified, altered without departing from the spirit and scope of this disclosure.

For a non-limiting example, an electrode pad can have several sections, e.g., a two piece electrode pad with the controller device snapping onto one side and each electrode pad piece shaped with the “Shuriken” design with an electroconductive wire between the two electrode pad pieces.

Some variations of these embodiments can be:

A disposable system, where the controller is attached to the electrode pad which has a limited service life and the electrode pad alone is thrown away after its service life has expired;

The controller is “integrated” into the electrode pad, being built and fabricated as a non-detachable single piece unit. Such a system could also have a limited service life, wherein the entire system is disposed of; and

The controller could have a wireless chip, communicating information, status, etc. wirelessly to a remote device, such as, for example, a smart phone. This would be beneficial for situations where the user could choose different treatment options (e.g., low back, knee, elbow, etc.), query to determine the “stage” of treatment, percent of current flow being transferred through the tissue to the reference electrode, health of controller battery, etc.

Therefore, it should be apparent that various modifications and changes may be made without departing from the spirit and scope of this disclosure.

FIGS. 6A, 6B and 6C are illustrations of alternate self-contained controller shapes with external electrode connectors. FIG. 6A is an illustration of a “cylindrical” controller housing 610 with indicator “light” 620 and reset/power button 625 on its surface. Ends of the housing 610 contain external electrode connectors 630 which can be plugged into to whatever connector arrangement is found on the pad (not shown) or contacting element. In one embodiment, the external electrode connectors 630 can be rigid male pins, to mate female connectors on/in the pad/contacting element. Of course, other types of connectors may be devised, according to design preference.

FIG. 6B is an illustration of another “cylindrical” controller housing 650, with indicator “light” 660 and reset/power button 665 on its surface. Ends of the housing 650 contain flexible lines terminated with electrode connectors 675 which can be connected to whatever connector arrangement found on the pad (not shown) or contacting element.

FIG. 6C is an illustration of an electrode connector extension 680, having a male style connector 685 on one side and a female style connector 685 on the other side. This extension embodiment contemplates having the controller connected in a non-rigid fashion to a pad (not shown) or contacting element.

It should be appreciated that while the above embodiments are described in the context of an enclosed controller administering electro-therapy via contact through a pad (or electrode extension) to the subject, via electrical waveforms shaped as further detailed below, the actual shape/design of the controller and/or pad and/or extension may be altered, modified according to design preference. So, if design preference is to apply the above embodiments, for example, to a laboratory situation or medical environment, the above designs may be easily modified to provide the desired effect. For example, if the subject is laboratory-housed tissue or culture of cells, etc., the contacts of the controller can be redesigned to allow the appropriate signals to be fed to the tissue or culture of cells, to the appropriate subject contacts. Accordingly, in these and other instances, different designs/implementations of the controller and its contacts/electrodes, etc., with consideration of the nature/type of electrical signals being generated to achieve the respective effect on the subject material, may be contemplated without departing from the spirit and scope of this disclosure.

FIG. 7 is an illustration 700 of an embodiment rudimentally applied to a flask of cultures. Exposed controller device 710 has its electrode channels connected by simple alligator clips 720, 725 to rod electrodes 730, 735. The rod electrodes 730, 735 are submerged into culture solution 740 that is housed by flask 750. This embodiment illustrates the application of an embodiment without a corresponding electrode pad and is demonstrative of the multiple “subject” applications possible.

FIG. 8 is a plot 800 of one embodiment of a representative signal waveform. The time-harmonic or frequency based waveform is composed of high frequency f₁ signal 810 being amplitude modulated according to a lower frequency f₂ signal to form a fixed separation (or current intensity window—CIW) having a minimum 820 and maximum 830 envelope. It is evident that this signal waveform is wavelike in form and has a positive DC offset of approximately 20 uA, with a cyclical amplitude modulation range of 20 uA. The combination of the two frequencies (f₁, f₂) and offset generates a current signal that has a 50 uA peak and a 10 uA floor, but fluctuates between the peak and floor values. In this example, the lower frequency (carrier) f₂ is one-tenth the frequency of the higher frequency f₁ signal. A corresponding set of frequencies would be 3 Hz and 30 Hz, or 10 Hz and 100 Hz, and so forth. Of course, other frequency ratios may be used, according to design preference, as well as DC offsets.

The intertwining of the high frequency f₁ signal 810 within the CIW envelope creates a current “density” within the CIW, that more slowly fluctuates in overall amplitude with the lower frequency modulating signal 830. This provides a unique electro-therapy signal profile, one that fluctuates very rapidly within a small time frame (aka—high frequency signal f₁), while in the aggregate (CIW) fluctuates very slowly (aka—low frequency signal f₂). Further, with the DC offset, a total of three effects are being applied simultaneously.

The embodiment of FIG. 8 shows one configuration where the core amplitudes of the low and high frequency signals are fixed (f₁ relative displacement is 20 uA, and f₂ relative displacement is 20 uA, where the composite signal is different). If either f₁ or f₂ are not amplitude fixed (held constant), then the composite signal will have a different profile (the CIW envelope will change), but still provide multiple frequency dependent signal effects that are beneficial.

FIG. 9 contains graphical representations of various amplitude modulated signals, bounded by two varying microamperage values. Referring to example A, higher frequency signal 910 is amplitude modulated with a lower frequency signal 920, to form a CIW envelope that is symmetric across the 50 uA midline (a DC offset of 50 uA is implicit). This example contemplates a larger high frequency “swing” from peak-to-trough, the high frequency swing becoming smaller for a period and then larger and then repeating, as a function of the lower frequency signal 920, as seen in the humps of example A. This particular embodiment shows a max current applied as 100 uA, and a min current applied as 0 uA, with a CIW that varies in aggregate current “density” in accordance to the lower frequency signal 920 component. This can be further extrapolated to form a “pulsing” wave or other variations.

Referring to example B, high frequency signal 950 is amplitude controlled by the low frequency signal having its peak 960 and trough 970. Here, the amplitude of the low frequency signal is held constant while the high frequency signal 950 is “rippled” over the low frequency signal. In this example, the high frequency signal is at 30 Hz, while the low frequency signal is at 2 Hz. Evident in this example is the fact that the CIW (excursion of one cycle of high frequency signal 950) envelope is very small in comparison to the overall low frequency range (excursion of one cycle of low frequency signal).

These embodiments demonstrate a non-user controlled electrotherapeutic technique of systematically modulating the device's output parameters by superimposing multiple waves upon each other allows the application of low microamperage current intensity for longer treatment durations on humans and animals with decreased time to effectiveness, improved treatment efficacy and expanded treatment capabilities over prior art devices. Other embodiments are anticipated and this disclosure only serves as an introduction to the fundamentals of the concept.

Modifications and variations to the above current/signal profiles are contemplated in the context of therapeutic or biological treatments. One example of a variation is by changing the intensity of the output current in a predetermined sequence (increasing and decreasing the microamperage intensity “quickly or gradually” over time between a maximum and minimum value in a stepwise fashion) while keeping the AC frequency and/or DC current and other output parameters that are superimposed on the changing current intensity constant over a period of output time. One non-limiting example would be, 15 uA at 40 Hz for 2 seconds followed by 20 uA at 40 Hz for 2 seconds followed by 25 uA at 40 Hz for 2 seconds followed by 30 uA at 40 Hz for 2 seconds, followed by 25 uA at 40 Hz for 2 seconds followed by 20 uA at 40 Hz for 2 seconds followed by 15 uA at 40 Hz for 2 seconds, etc. Of course, the time periods, frequency, and amplitude may be of different values, according to design preference.

Another example of a variation is by changing the intensity of the output current in a predetermined sequence (increasing and decreasing the intensity “randomly” over time) while keeping the AC frequency and/or DC current and other output parameters that are superimposed on the changing current intensity constant while changing the duty cycle (amount of ON time vs. OFF time within a waveform) of the output in a predetermined systematic way.

Another example of a variation is by changing the intensity of the output current in a predetermined sequence (increasing and decreasing the Intensity randomly over time) while keeping the AC frequency and/or DC current superimposed on the changing current intensity constant while changing the duty cycle (amount of ON time vs. OFF time within a waveform) of the frequency output in a pulsed manner that can be measured in pulses per second or Hertz.

Another example of a variation is by changing the intensity of the output current in a predetermined sequence (increasing and decreasing the microamperage current intensity randomly over time and randomly as a discrete output packet of time duration) while keeping the AC frequency and/or DC current constant and superimposed on the changing current intensity while changing the duty cycle (amount of ON time vs. OFF time within a waveform) of the output in a random pulsed manner that can be measured in pulses per second or Hertz.

Another example of a variation is by changing the intensity of the output current in a predetermined sequence (increasing and decreasing the microamperage current intensity quickly or gradually over time, e.g. systematically as in a step-wise increase and/or decrease of the microamperage level of current intensity output) while changing the AC frequency and/or DC current specifically, systematically and/or randomly and superimposed on the changing current intensity level.

Another example of a variation is by changing the intensity of the output current in a predetermined sequence [increasing and decreasing the intensity in a waveform manner, (e.g. sine wave, square wave, triangle wave, etc.) and quickly or gradually over time and quantified in Hertz or cycles per second, (e.g., a 3 Hz sine wave for 1 minute moving between a lower and a higher microamperage “window of intensity” that said window can vary systematically and/or randomly and sequentially, etc.)] while keeping the AC frequency and/or DC current specific and/or systematically and/or randomly changing and superimposed on the modulating current intensity “waveform.”

Another example of a variation is by changing the intensity of the output current in a predetermined sequence [increasing and decreasing the intensity in a waveform manner, (e.g. sine wave, square wave, triangle wave, etc.) and quickly or gradually over time and quantified in Hertz or cycles per second, (e.g., 3 Hz sine wave 1 minute, 40 Hz square wave 3 minutes, etc.)] while changing the AC frequency (including or excluding DC current) systematically (for example with a predetermined sequence, an algorithm, a randomizer and a look-up table, a random value generator, etc.) and superimposed on the modulating current intensity “waveform.”

Another example of a variation is by changing the intensity of the output current in a predetermined sequence [increasing and decreasing the intensity in a waveform manner, (e.g. sine wave, square wave, triangle wave, etc.) and quickly or gradually over time between a higher and lower level of microamperes (which acme and nadir can vary at different times) and quantified in Hertz or cycles per second] while changing the AC frequency (including or excluding DC current) in a specified manner (e.g., according to a look-up table) and/or randomly and/or according to an algorithm. For example, a current intensity modulated as a 3 Hz sine wave between a CIW of 10 and 30 microamperes with an AC frequency of 970 Hz square wave superimposed on this 3 Hz current intensity “wave” for 60 seconds followed by a current intensity modulated as a 40 Hz triangle wave between a CIW of 15 and 25 microamperes with an AC frequency of 116 Hz sine wave superimposed on this current intensity wave for 30 seconds, etc.

Another example of a variation is by lowering the intensity of the output current to a range that changed according to the variability scheme of the programming to be below 1 milliamp and increasing the duration of the use of the device to a longer total treatment time. Such a configured device can be worn continuously over many hours with a current intensity setting that is below the point of concern for the user or below the point that significant sensation can be felt or muscular stimulation could occur. By increasing treatment time while decreasing, but varying the intensity of the output current in a waveform-like fashion simultaneously with other output characteristics such as AC frequency, etc., beneficial treatment results were able to be obtained more quickly than with traditional devices.

Various embodiments described have been experimentally shown to minimize treatment plateaus, accommodation, habituation or tachyphylaxis.

Another example of a variation is by using a multi-channel device whereby the intensity of the output current is modulated in a waveform-like fashion and can be synchronized or desynchronized between the various channels while keeping the AC frequency and/or DC current treatment packets constant (e.g. 3 Hertz on channel A and 3 Hertz on channel B) or systematically varying (e.g. 3 Hertz on channel A and 116 Hertz on channel B) and/or by varying systematically or randomizing the synchronization or desynchronization or both over a period of output time.

Another example of a variation is to systematically and/or randomly or both, continuously change all the parameters of output. An software-encoded algorithm is anticipated to direct the output in this manner.

Another example of a variation is being able to sweep through various intensity output current conditions either in an increasing sweep or decreasing sweep (e.g. sweeping from 0-100 uA, then 90-60 uA, then 25-75 uA, then 30-15 uA, etc. over a period of time) while the AC/DC frequency function is sweeping through various frequencies (e.g. 1-1,000 Hz, then 1-3 Hz, then 40-100 Hz, etc.) over the same or different period of time.

Another example of a variation is to have the “Duty cycle” pulsed.

As apparent from the above embodiments, it is believed the non-user controlled modulation of electrical current intensity, and/or systematically varying (waveform-like modulatation), and/or with DC positive and/or negative current level, and/or in combination with other electrical output parameters such as AC frequency modulation are new to at least the field of TENS devices. Further, experiments with the above embodiments have shown increased efficacy on the healing of equine, canine and human tissues and physiologic functions beyond the pain blocking effects produced by prior art TENS devices.

Accordingly, the use of this new electrotherapeutic technique is foreseen to have beneficial effects on human, veterinary, plant and other biological tissues and physiologic functions in vivo and in vitro that are not able to be attained by modulation of the other output parameters alone, such as found in the prior art methods of manually adjusting and modulating intensity, frequency, frequency sequences, frequency combinations in dual channel devices, polarity, duty cycle, waveform, single or multiple channel devices, interferential devices, etc.

Various embodiments in consideration of the new signal manipulation scheme is contemplated for use in traditional TENS/MENS applications. For example, one embodiment demonstrates an On/Off switch user activated miniaturized human and veterinary TENS/MENS/Iontophoresis device, with non-user controlled microcurrent output that delivers a preprogrammed waveform modulated intensity function with other output parameters superimposed on the modulated intensity. Another embodiment discloses the manipulation and modulation of the electrical current intensity both singly and in combination with systematic and/or random modulation of the other output parameters, such as frequency, frequency sequences, duty cycle, waveform, sweeps, polarity, single or multiple channel outputs, interferential, etc. for human and veterinary electro-therapy systems such as TENS/MENS/Iontophoresis, as well as in vitro plant and/or animal cellular culture systems and cellular electroporation.

One embodiment allows a user to place a self-powered electrode(s) on the skin like a large band-aid, and connect a single channel device wirelessly to the self-powered electrode. The user can turn it on and let the program run until the user turns the device off

With the non-supervisory, self-contained system, therapy can be implemented while conducting activities, for example, household chores, or while sleeping, thus saving a great deal of time going to doctors to receive therapy. This also allows for longer electro-therapy treatment durations with improved effectiveness.

By reducing the various aspects of several different embodiments to practice and conducting animal experiments on horses, dogs, as well as humans, it appears reasonably foreseeable that the ability to affect various tissues or organ function as well as various physiologic functions, such as tissue repair, perfusion, nitric oxide induction, hormone modulation, anti-inflammation secondary to various sources (e.g., cytokines, trauma, neuropeptides, etc.), blood pressure, vascular condition, pain of many origins and sources, nausea, emesis, wounds, orthopedic, nerve function, mood or psychological condition, or other organ or tissue function such as: connective tissue matrix, heart function, penile or clitoral perfusion, kidney, liver, pancreas, bladder, prostate or any other viscera or gland, ocular, dental health, etc. over a number of days, weeks, months, years or decades.

Accordingly, one embodiment enables a user to treat an area of the skin and lower blood pressure and/or inflammatory markers with or without other medication over a period of time sufficient that treatment could influence the development of other cardio-vascular conditions. Another embodiment enables a user to electrically stimulate cell culture systems in vitro and obtain enhanced effects over the prior art methods. Another embodiment enables a user to electroporate compounds of interest into a group of cells in vitro and obtain enhanced effects over the prior art methods. Another embodiment enables a user to electrically extract botanical compounds of interest without damaging heat sensitive constituents of the plant base material.

TENS/MENS/Iontophoresis output controller (and anticipates a multi-channel device) that is activated by the only user control, an ON/OFF switch, that activates firmware (hardware components, microchip and software programming) and has its intensity output current controlled by this firmware and has its output frequencies very accurately controlled by the firmware and a quartz timer and current controlled by the firmware with or without a voltage regulator and is powered by a 3 volt coin battery.

“Smart electrodes” are envisioned to be used with the device such that some of the components of the device are split between the electrode and the driver device. The electrode and device will act as a “Lock and Key” system such that the device will not operate unless it recognizes specific components, some could be “dummy,” some could be “nonsense,” some could be active, some could be coded or encrypted in such a way that the electrodes engineered without these components will not work. These smart electrodes could have a microchip and/or other components attached to a PCB board or flex circuit built into the electrode in such as way as the device will not operate unless it recognizes these components and various codes on the smart electrode. The operating system could also be split between two “Lock and Key” microchips, one portion on the device and another on the electrode, thereby increasing the security that a compatibly engineered electrode was used with the device and impairing the ability of poorly engineered products to be substituted for use with the device.

Another embodiment of a Smart Electrode Lock and Key design is with an RFID built into the electrode with a coded signature that can communicate with the device and determines its authenticity thereby impairing the ability of poorly engineered products to be substituted for use with the device.

Other Smart Electrode embodiments are envisioned such as the “Smart PEMF” electrodes that has components such as microchips, mini-inductors, capacitors, magnetic chips, or a PEMF loop built into the electrode that, in combination with the device driver can sequentially fire discrete micro electromagnetic pulses that are geometrically shaped to produce a virtual “electron massage” effect.

Other Smart Electrode embodiments are envisioned such as one that has components built into the electrode that is programmed to be a sensor, reporting back to the driver device and providing a form of feedback loop to adjust the output according to the information collected. The program could sense when the electrode is worn out and send a signal to an indicator so that therapy is not attempted with an electrode that is no longer usable.

Another smart electrode embodiment is envisioned with specific design patterns layered into the electroconductive portion of the electrode as a technique to influence the spatial shaping of the electrical current flow as well as the mixing of currents in multi-channel systems.

Another electrode embodiment is envisioned with different materials for inclusion in the electroconductive hydrogel component of the electrode. For instance, by adding colloidal silver at about 25 ppm or more the hydrogel material will be rendered bacteriostatic, thereby decreasing the likelihood that the patient would get a dermal infection or cross-contaminate someone else handling the product. This is important for wound care, skin care and other infection treatment products such as shingles treatment electrodes. A good example of a beneficial application of this technology to equine electrodes would be ringworm. One horse with Ringworm can spread the infection throughout the entire barn. If you use the same electrode on different horses, you could cross-contaminate, so a colloidal silver impregnated gel electrode could have some protective benefits especially in the dirty barn setting. Plus the silver would likely facilitate conduction through the hydrogel improving electrode performance. Studies have shown an average of 13% of equine veterinary personnel are colonized with primarily the equine related genotype of Methacillin Resistant Staphylococcus Aureus (MRSA). So anything that can prevent zoonotic transmission of germs to veterinary personnel or to other horses from handling electrodes would be a helpful improvement. At this level of concentration colloidal silver is typically hypoallergenic and much less toxic and caustic than other types of antimicrobial compounds.

Another electrode embodiment is envisioned with the layer above the hydrogel being composed of an photo-emitting electrosensitive material so that when the current was flowing the gel would glow thereby creating an indicator light. This gel could be inlaid in the outer edge so that the edge of the electrode glowed or backed on the whole electrode surface or discrete sections so that they glowed and with the electrode foam backing cut away in the design of company branding,

The below matrix in Table 1 describes one possible “control” program for treatment. This is programmed as a sequence of discrete output events at a specific current intensity for a specific time duration, upon initiation. For this example, the program generates a CIW 15 uA-30 uA window and runs for 4 hours. 1,443 coded lines are called out, each line code segment calls for a 10 second output duration event, encapsulated in the 223 steps below. At the end of the 4 hour program the device cycles back to line 1 to repeat the program.
